Hi After using the terminal to do a system update using the following commands.sudo apt-get update & sudo apt-getdist-upgrade I have no network configuration when starting the computer. I can get the network back by shutting down rebooting in safe mode and enable networking from the list. then click on resume normal re boot.
the error message reads: waiting for network config
waiting 60 more seconds for network config.
boot system without full configuration.
Any help would be much appreciated, Thank you in advance.
